Creality Ender 3 Filament Guide Roller

thingiverse

I used this part as a filament guide for my Ender 3 printer. Its purpose was to protect the inlet of the extruder from wear caused by the filament rubbing against it. I had an extra 22mm OD, 8mm ID, and 7mm wide skate bearing that served perfectly as the rolling element. To ensure a proper fit, if the slot is too loose, simply apply tape to the metal flange on the printer until it fits snugly. This design was created using Fusion 360.
